Tested using 5 watts VHF 5 watts at half way sensitivity 1 feet away. Meter shows half of deflection. No battery is required, see attached pictures, maybe good for testing nearby transmitters.

Simple Field Strengh Meter to adjust transmitters or check its proper operation. Comes with an antenna that can be plugged in the top SMA connector. Works fine at least until 100 MHz I tested it. It came alone in a plastic bag without protection of any kind; fortunately it was not damaged during transport
